I bought my M3 note in Chine in May. Always had A version of the Firmware, but now I see official G version.
Before making any mistake, I want to be sure I can install it as any other version of A firmware, as I 'm not sure to have the ‘valid’ model mentioned in flymeos forum: both L91 and M91.
My model serial number is 91QEBNM2CE8P

@thierrite it should be. However, as of now I didn’t heared it is possible on the m3 note.
As you might have heard or seen already bypasses exist for other devices, but as of now I am not aware of a m3 note one.
Maybe give it some time and someone will come up with a proper solution.
